Investors are totally cool with that. Amazon (NASDAQ: AMZN) shares during the last three years have doubled to more than $330, even though everyone knows the company probably won't be profitable anytime soon.

Another one of those ventures is groceries. Amazon could be the company you buy groceries from in the not-so-distant future. It is expanding its AmazonFresh service, which could (buzzword alert) disrupt the industry by delivering groceries to people's homes. There are other companies that do that, but none of them have Amazon's scale. Although Amazon does not have immediate plans to launch the service in the mid-Atlantic region, things happen fast with Amazon.

Amazon does not own the Washington Post. Amazon founder Jeff Bezosacquired the Post for $250 million of his own money. The deal did not involve Amazon.
